Description

  The present invention relates to an infusion bag / bottle storage bag and a method of using and manufacturing the same. More particularly, the present invention relates to a bag for containing an infusion bag or infusion bottle, particularly used in the medical field, and to a method for using and manufacturing such a bag.

  Currently, there are surgical treatment, radiation therapy and chemotherapy as the main treatments for cancer. Such treatment is carried out alone or in combination depending on the type of cancer and the general condition of the patient. Among them, chemotherapy is a method in which an anticancer drug is administered as an infusion solution or the like to kill cancer cells, and generally has a medicinal effect on the whole body.

  Anticancer drugs are not used for all cancers in the same way, and it is necessary to change the type of anticancer drug depending on the site and stage of cancer. This means that the types of anticancer agents differ depending on the cancer patient, and prescriptions suitable for individual cancer patients are made. Therefore, an operation of mixing preparation (mixing) is generally performed for preparation of an anticancer agent. The anticancer agent prepared by mixing is finally obtained in a state of being stored in an “infusion bag” or “infusion bottle” and used as an infusion solution of the anticancer agent.

  Here, the anticancer agent itself exerts a killing effect on cancer cells, but also acts on other cells at the same time. In other words, since it can act not only on cancer cells but also on normal cells, careful handling of anticancer agents is necessary. In light of this point of view, it is important to take measures so that not only patients but also medical workers who handle infusions of anticancer drugs are not exposed to anticancer drugs.

  To prevent exposure to anticancer agents, it is conceivable to prevent exposure that may occur when preparing anticancer agents for mixing or preparing for administration at the bedside of a patient. The inventor of the present application has noticed the problem of exposure to an anticancer drug particularly related to the handling of an infusion bag or an infusion bottle (hereinafter also referred to as an “infusion bag / bottle”), and has found a need to take countermeasures therefor.

  Specifically, the present inventors have found that there are the following problems. In the case of mixing preparation and priming by a pharmacist, the anticancer drug may be scattered or leaked. However, since the pharmacist wears gloves, the risk of exposure is generally low. Although the pharmacist himself is not exposed, there may be anticancer drugs attached to the infusion bag after mixing preparation and priming, and for those who handle the infusion bag after that. Are at risk of exposure. In other words, those who handle infusion bags filled with anticancer drugs may be unknowingly at risk of exposure to anticancer drugs. More specifically, when the nurse / patient himself / herself administers an anti-cancer drug using the “infusion back bottle provided by the pharmacy department of the hospital”, the infusion back bottle is naturally handled by hand. Work may be required, but the anti-cancer drug may already be attached to the outer surface of the infusion bag, thus nurses / patients may be exposed to the anti-cancer drug .

  The present invention has been made in view of such circumstances. That is, the main object of the present invention is to provide a technique / means that contributes to the prevention of anticancer drug exposure or the reduction of anticancer drug exposure particularly related to the handling of infusion bag bottles.

In particular, the dimension of the “non-overlap portion” located between the “bottom of the inner bag” and the “open end of the outer bag” is larger than the dimensions of the connecting parts attached to the stopper of the infusion bag / bottle. It is preferable that

  In the present invention, the infusion bag may be an anticancer drug bag or an anticancer drug bottle used for cancer treatment, and therefore the bag of the present invention may be a bag used for cancer treatment. . That is, the infusion bag / bottle storage bag according to the present invention is preferably a cancer treatment bag. In addition, since the infusion bag and bottle stored in the bag can be transported as it is stored, the infusion bag and bottle storage bag according to the present invention is not only a storage bag but also a transport bag. .

  Furthermore, the infusion bag / bottle storage bag according to the present invention is not only a storage bag / transport bag for storing or transporting the infusion bag / bottle, but also a disposal for discarding the infusion bag / bottle. It is a bag. In particular, it is a “storage bag / carrying bag” and a “disposal bag” for use in cancer treatment. In other words, the infusion bag / bottle storage bag according to the present invention is preferably a bag for storage / transport / disposal for cancer treatment.

  In particular, when it is a “discard bag”, the infusion device in which the inner volume of the bag formed in the inner region of the “bottom of the inner bag” and the “sealing mechanism of the outer bag” is connected to the infusion bag Has a volume capable of storing at least. That is, when sealing is performed to close the sealing mechanism of the outer bag body, the volume that the space formed between the “bottom of the inner bag body” and the “sealing mechanism of the outer bag body” can have is the infusion solution. The volume is preferably larger than the volume of the infusion device connected to the back bottle. In the present specification, the “infusion device” refers to a device / part that contributes to infusion supply from an infusion bag / bottle, for example, although not particularly limited, an infusion tube and / or “exposure prevention”. It means various connection parts related to infusion operation such as “system”.

  In still another preferred aspect, the infusion device is attached in advance to the “notch opening provided in the bottom of the inner bag”. That is, the infusion bag / bottle storage bag according to the present invention has an infusion device required for the infusion bag / bottle or a part of the device in advance in the “notch opening” (more precisely, “inner bag” You may have the form attached to the bag body part around the notch opening part provided in the bottom part of the body.

The present invention also provides a method of using the infusion bag / bottle storage bag described above. About this, the "use method of the infusion bag / bottle storage bag" of the present invention,
(A) keeping at least a part of the outer bag body upside down so that the outer surface of the outer bag body is not exposed;
(B) Insert the infusion bag from the open end of the inner bag and place the infusion bag in the inside of the inner bag, and (c) Unwrap the outer bag and turn the outer bag The infusion bag is accommodated in a double bag consisting of an inner bag.

  One of the features of the method of use of the present invention is the handling of the infusion bag / bottle storage bag when the infusion bag / bottle is stored. Specifically, the infusion bag / bottle storage bag is turned over so that the outer surface of the outer bag body is not exposed, the infusion bag / bottle is stored in the storage bag in the inverted state, and then the outer bag body is turned over. Solve the state.

  In a preferred embodiment, the outer bag body is turned over prior to the preparation of the infusion solution for the infusion bag. That is, the outer bag body is provided in a state of being turned over in advance prior to the preparation for supplying the infusion back bottle to the actual medical site. For example, such preparation is a mixed preparation performed to obtain an infusion bag filled with an anticancer agent of an individual cancer patient, and the outer bag body prior to the mixed preparation of such an anticancer agent. Keep it upside down.

  In a preferable aspect, in the above (a), the outer bag body is provided in an inverted state so that at least one fold is provided in the outer bag body or the outer bag body is rolled up. .

  In a preferred aspect, in the above (c), the user unwinds the outer bag body without touching the outer surface (original outer surface) of the outer bag body. That is, the person who handles the infusion bag / bottom bottle unfolds the outer bag body under the condition that only the inner surface is touched without substantially touching the outer surface (original outer surface) of the outer bag body.

  In a preferred aspect, after the above (c), the open ends of both the inner bag body and the outer bag body are sealed. That is, after the infusion bag / bottle is stored inside the inner bag body, an operation of closing the two opening ends of the infusion bag / bottle storage bag facing each other is performed.

  In the above (b), it is preferable to store the infusion bag so that the connecting part attached to the stopper of the infusion bag bottle protrudes from the notch opening of the inner bag. That is, it is preferable that the infusion bag is placed inside the inner bag body so that the connecting part penetrates the notch opening of the inner bag body.

  In a preferred embodiment, the infusion bag is once in a state in which the infusion bag is once stored in the infusion bag and bottle storage bag, and is not taken out from the infusion bag and bottle storage bag. That is, the infusion using the infusion bag is performed in a state where the infusion bag / bottle storage bag used for storage covers the infusion bag / bottle as a whole. In addition, it is preferable that the flange part of the connection part of an infusion back bottle is supported by the inner bag body around a notch opening, thereby preventing the connection part from being detached from the infusion back bottle. In other words, the flange part of the connecting part of the infusion bag / bottle does not remove the connecting part from the infusion bag / bottle during the infusion. It is preferably supported by the “bag body part)”.

  In one preferred embodiment, after infusion, the bag is used as a waste bag by keeping the infusion bag in the bag. That is, after infusion, the bag is used as a waste bag without removing the infusion bag once from the bag. In such a case, it is preferable to reseal the bag by closing the sealing mechanisms of the open ends of both the inner bag body and the outer bag body. In other words, at the time of disposal, the “sealing mechanism for the opening end of the inner bag body” and the “sealing mechanism for the opening end of the outer bag body” are respectively functioned to perform “closing operation” that contributes to sealing the bag, thereby performing sealing. Moreover, when using it as a waste bag, it is preferable to store the infusion device connected to the infusion bag / bottle inside the bag. In other words, when used as a waste bag, it is preferable to place not only the infusion bag and the infusion device but also the infusion device inside the bag. More preferably, when used as a waste bag, not only the infusion bag and the infusion device but also the infusion device inside the bag (particularly the space formed between the “bottom of the inner bag body” and the “sealing mechanism of the outer bag body”). And reseal the bag, and discard the resealed bag with its contents (ie, the infusion bag and infusion device contained in the bag). Such an aspect corresponds to an aspect in which the infusion device is placed in a bag and discarded without being removed from the infusion bag.

The present invention also provides a method for producing the infusion bag / bottle storage bag. In this regard, the “method for producing an infusion bag / bottle storage bag” of the present invention is:
(I) a step of preparing an inner bag and an outer bag,
(Ii) “The inner bag body is positioned relatively on the inner side so that the opening end of the inner bag body and the opening end of the outer bag body form an opening end facing each other of the infusion bag / bottle storage bag. Projecting the "open end" from "the bottom of the outer bag body positioned relatively outside", and (iii) joining the bottom of the outer bag body and the inner bag body to each other.

  One of the features of the manufacturing method of the present invention is that the opening end of the inner bag body and the opening end of the outer bag body respectively constitute “two opening ends of the infusion bag / bottle storage bag facing each other”. Thus, the opening end of the inner bag body is exposed from the bottom of the outer bag body, and then the bottom portion of the outer bag body and the opening end region of the inner bag body are joined to each other.

  According to the present invention, it is possible to suitably prevent or reduce exposure to anticancer agents related to handling of infusion back bottles. In particular, even if anticancer drugs adhere to the infusion bag or bottle due to splashing or leakage during mixing preparation or priming, the risk of subsequent exposure to the infusion bag or bottle is reduced. .

  Specifically, in the infusion bag / bottle storage bag of the present invention, the final outer surface after the infusion bag / bottle is stored is not contaminated (or reduced in contamination) by the anticancer agent. Thus, the risk of exposure to anticancer drugs is reduced for those who use infusion bags.

  The description will be as follows in view of the actual usage. When using the infusion bag / bottle storage bag of the present invention, the outer bag body is placed so that the outer surface of the outer bag body is not exposed, while the outer bag body is exposed so that at least a part of the inner surface of the outer bag body is exposed. Turn it over. In this way, the “infusion bag / bottle with an anticancer drug possibly attached” is stored in the infusion bag / bottle storage bag in the inverted form. During storage, the exposed surface of the infusion bag / bottle storage bag may be contaminated with an anticancer agent. However, the exposed surface is a part of the inner surface of the outer bag body and the outer surface of the inner bag body. Since it corresponds to “a part”, it does not form the outer surface of the infusion bag / bottle storage bag. In other words, after the infusion bag and the bottle are stored, the outer bag body is turned upside down, so that the “external part of the outer bag body” and the “inner bag body” that formed the exposed surface of the bag before and during storage. "Part of the outer surface of the bag" becomes the inner surface of the infusion bag / bottle storage bag, but does not form the exposed surface of the bag before and during storage, and therefore is not contaminated. Will form the final outer surface of the infusion bag / bottle storage bag (see FIGS. 9 and 10 to be described later). Therefore, the infusion bag / bottle storage bag containing the infusion bag / bottle is not finally contaminated with the anticancer agent on the outer exposed surface, and the person who handles the infusion bag / bottle does not know after that. The risk of exposure to is eliminated.

Here, the “longitudinal axis A _{inner bag} ” means an axis in the longitudinal direction and the length direction extending through the central portion of the width of the inner bag body (see the lower left diagram in FIG. 2). . Similarly, the “longitudinal axis B _{outer bag} ” means an axis in the longitudinal direction and the length direction extending so as to pass through the center of the width of the outer bag body (see the lower right diagram in FIG. 2). ). As can be seen from the embodiment shown in FIG. 2, in the infusion bag / bottle storage bag 300 of one preferred embodiment, the longitudinal axis A _{inner bag} of the inner bag body 100 and the longitudinal axis B _{outer bag of the} outer bag body The inner bag body 100 and the outer bag body 200 are aligned with each other so that they are parallel or coincide with each other. In such an embodiment (especially the “matching” embodiment), the infusion bag and bottle storage bag 300 (particularly its plan view) has its longitudinal axis (ie, the longitudinal axis A _{inner bag} or the longitudinal axis B _{outer bag).} It may have a line-symmetric form around

  As shown in FIG. 3, in the infusion bag / bottle storage bag 300 of the present invention, a notch opening 140 is provided at the bottom of the inner bag body 100. That is, “the opening 140 formed by partially cutting the inner bag” is provided in the bottom 120. As shown in the drawing, the notch opening 140 is preferably provided at the substantially central portion of the bottom of the inner bag body 100. The notch opening 140 can be used as an opening for an infusion device connected to an infusion bag. For example, as shown in parentheses in FIG. 3, the notch opening 140 can be used as an opening for the connecting part 550 of the infusion bag 500. Specifically, the notch opening 140 serves to extend the connection component 550 attached to the stopper of the infusion bag / bottle from the inside of the inner bag body 100 to the outside. When using the infusion bag / bottle storage bag, as shown in FIG. 4, the infusion bag / bottle storage bag 300 can be suspended so that a part of the connecting part 550 is exposed from the inner bag body 100. Infusion is possible.

  The infusion bag / bottle storage bag 300 is particularly characterized in that the notch opening 140 contributes to preventing the connection component 550 from being detached. The infusion bag / bottle storage bag 300 of the present invention can be used not only for storing the infusion bag / bottle but also for drip infusion, but the connecting component 550 does not come off the infusion bag / bottle during drip use. Thus, the notch opening 140 can function suitably. Conventionally, as shown in the lower right parenthesis of FIG. 4, when the infusion bag 500 'is directly suspended from the hook portion 400' or the like, the connecting component 550 'is separated from the infusion bag 500'. There was concern that it would come off. Specifically, conventionally, when the drip tube 570 ′ or the like extending from the connection component 550 ′ is accidentally pulled, a force is generated between the connection component 550 ′ and the infusion bag 500 ′. As a result, there is a possibility that the connecting component 550 ′ may come off from the stopper of the infusion bag 500 ′. If the connecting part 550 'is removed, an infusion solution such as an anticancer agent filled in the infusion bag 500' may leak at that time, which may expose the anticancer agent to exposure.

  The notch opening 140 according to the present invention functions so that the periphery thereof supports the flange portion 550a of the connection component 550 (see the lower side of FIG. 4), so that the drip tube 570 is assumed to be accidentally pulled. However, excessive force is not generated between the connecting part 550 and the infusion bag 500, and as a result, the connecting part 550 is prevented from being detached. More specifically, even if a downward force is applied to the connection component 550 due to accidental pulling of the drip tube 570 or the like, the flange portion 550a of the connection component 550 is disposed around the notch opening 140. Since it is locked to the bag body, the force is effectively absorbed. That is, due to the bag body around the notch opening 140, the “reaction force” acts on the flange portion 550a with respect to the downward force acting on the connection component 550. -The force which mutually pulls away between the bottles 500 is not produced substantially. By effectively exhibiting the effect related to the notch opening 140, the connection component 550 is prevented from being detached from the infusion bag. From this point of view, the notch opening 140 provided in the inner bag body 100 can also be referred to as a “detachment prevention opening” for the connecting part of the infusion bag / bottle.

The form itself of the cutout opening 140 as the “detachment prevention opening” is not particularly limited, and may be a rectangular shape, a regular square shape, a circular shape, an elliptical shape, or the like. Since the size of the notch opening 140 may be any suitable size for preventing the connection component from being detached, it is preferably larger than the body portion of the connection component 550 but smaller than the flange portion 550a. For example, in the embodiment shown in FIG. 3, the short dimension D _{notch portion} is preferably about 3 mm to 13 mm, more preferably about 5 mm to 10 mm (for example, about 8 mm), while the long dimension D is the length of the _{notch portion.} Is preferably about 6 mm to 23 mm, more preferably about 9 mm to 17 mm (for example, about 14 mm).

  In the infusion bag / bottle storage bag 300 of the present invention, at least the outer bag body of the two components of the inner bag body and the outer bag body has sufficient flexibility or flexibility. More specifically, it is preferable that the outer bag body is flexible or soft enough to be folded or folded. In other words, the outer bag body having the double structure of the infusion bag / bottle storage bag can be turned upside down so that it is folded at least about 180 °, and even if it is turned over, physical damage such as cracking or chipping is substantially eliminated. Not to be triggered automatically.

  For example, the inner bag body and the outer bag body may be a bag body made of a plastic material. That is, the inner bag body and the outer bag body may each be made of a plastic film. Specific materials for the plastic film of the outer bag body and the inner bag body include low density polyethylene (for example, high pressure method low density polyethylene, linear low density polyethylene), medium density polyethylene, high density polyethylene, polypropylene (for example, , Inflation polypropylene, biaxially oriented polypropylene, unstretched polypropylene), polyolefin resins such as ethylene-propylene copolymer, polyester resins, polyvinyl chloride resins, polystyrene resins, polyamide resins, polybutene resins, poly Mention may be made of at least one selected from the group consisting of methylpentene resins, polyacrylic resins, polyacrylonitrile resins, vinylon and nylon. The film thickness of the inner bag body and outer bag body made of such a plastic film is not particularly limited, but is preferably 5 to 3000 μm, more preferably 10 to 1000 μm, still more preferably. Is 2 to 500 μm. When the film thickness of the bag is less than 5 μm, there may be a problem in strength of the bag, while when it exceeds 3000 μm, “sufficient flexibility” may be impaired.

  Moreover, it is preferable that the film which comprises an inner bag body and / or an outer bag body is a light shielding film (that is, it is preferable that an inner bag body and / or an outer bag body are light shielding bags). In particular, in order to suitably protect the infusion solution in the infusion bag / bottle, it is preferable that the film forming the bag is an ultraviolet blocking film. Although not particularly limited, an ultraviolet absorber may be mixed into the plastic film or the like, or a layer made of an ultraviolet cut material may be provided on the surface of the plastic film or the like. Such UV absorbers or UV blocking materials may be those known to those skilled in the art of infusion back bottles.

  In view of the aspect at the time of use, it is preferable that the infusion bag / bottle storage bag 300 of the present invention has the outer bag body turned over so that the outer surface of the outer bag body is not exposed. That is, the outer surface of the outer bag body is turned inside so that the outer surface of the outer bag body is not exposed, while the outer bag body is folded and turned over so that at least a part of the inner surface of the outer bag body is exposed. Is preferred.

  As shown in FIG. 5, for example, the outer bag body 200 may be turned over so that at least one crease is provided in the outer bag body 200. That is, the infusion bag / bottle storage bag 300 may be configured such that the outer bag body 200 is folded. In the case of “one crease”, as shown in the drawing, a substantially central point P in the length direction of the outer bag body 200 is a turning point, and the position of the opening end 210 of the outer bag body 200 changes. Thus, the outer bag body 200 is turned over so that the outer surface of the outer bag body is not exposed to the outside. Particularly preferably, the opened end 210 of the folded outer bag body 200 is located at the same position as or beyond the bottom 220 of the outer bag body 200 so that the outer surface of the outer bag body is not exposed. Further, in the case of “two folds”, as shown in the lower side of FIG. 5, the substantially center point P ′ in the outer bag 200 turned upside down in the case of “one crease” is the next folding point. Thus, the outer bag body 200 is placed so that the “folded portion of one fold” (that is, the folded portion obtained when there is one fold) is at the same position as the bottom of the outer bag body 200 or a position beyond it. The bag body 200 is turned over. In any case, in the infusion bag / bottle storage bag turned upside down, at least a part of the inner surface of the outer bag body is exposed, but the outer surface of the outer bag body is not exposed. If the transfusion bag / bottle storage bag 300 turned upside down is viewed as a whole, the inner bag body 100 protrudes from the folded outer bag body 200.

  As shown in FIG. 5, the infusion bag / bottle storage bag 300 with the outer bag body 200 turned upside down has an exposed surface of “a part 315 of the inner surface of the outer bag body” and “the outer surface of the inner bag body”. Part 316 ″ (see in particular the perspective view in parentheses in FIG. 5). In other words, the surface that may be contaminated with the anticancer agent when storing the “infusion bag / bottle with the possibility of attaching the anticancer agent” in the infusion bag / bottle storage bag 300 is “the outer bag” A part 315 "of the inner surface of the body and" a part 316 of the outer surface of the inner bag ". Therefore, when the outer bag is turned upside down after the infusion bag and the bottle are stored, the “part of the inner surface 315 of the outer bag body” and the “inner bag body” that formed the exposed surface of the bag before and during storage. A part 316 ”of the outer surface of the bag becomes the inner surface of the infusion bag / bottle storage bag, while the exposed surface of the bag is not contaminated before and during storage. The “outer surface” becomes the final outer surface of the infusion bag and bottle storage bag. Therefore, after the infusion bag is completely stored, the exposed outer surface is not contaminated with the anticancer agent, and the risk of exposure to the anticancer agent is reduced.

  The infusion bag / bottle storage bag 300 is not limited to a form in which the outer bag body 200 is folded, and as shown in FIG. 6, a form in which the outer bag body 200 is rolled up. It may be. Specifically, the outer surface of the outer bag body may be turned over so that the outer surface of the outer bag body is turned inside, and the outer end of the outer bag body is not exposed. It is like that. Even in such a form, in the infusion bag / bottle storage bag, at least a part of the inner surface of the outer bag body is exposed, but the outer surface of the outer bag body is not exposed. When the transfusion bag / bottle storage bag 300 turned upside down is viewed as a whole, the inner bag body 100 protrudes from the winding portion of the outer bag body 200. Even in the infusion bag / bottle storage bag having such a configuration, the exposed surfaces are only “a part 315 of the inner surface of the outer bag body” and “a part 316 of the outer surface of the inner bag body”. , Exposure to anticancer drugs is prevented. That is, when the wound state of the outer bag body is released after the infusion bag and the bottle are stored (that is, when the rolled up state is released), the exposed surface of the bag was formed before and during storage. A part 315 ”of the inner surface of the outer bag body and a part 316 of the outer surface of the inner bag body form the inner surface of the infusion bag / bottle storage bag, while the exposed surface of the bag before and during storage. The uncontaminated and uncontaminated “outer surface of the outer bag body” forms the final outer surface of the infusion bag / bottle storage bag, after which anticancer drug exposure is prevented.

  The infusion bag / bottle storage bag 300 of the present invention is suitable for storing infusion bags / bottles, and from that point of view, a sealing mechanism is provided at the opening end of at least one of the inner bag body and the outer bag body. It has been. In the present specification, the “sealing mechanism” refers to a mechanism capable of blocking the inside of the bag body from the outside of the bag body. Specifically, when the sealing mechanism is operated and put into the “closed state”, the inside of the bag body and the outside of the bag body can be blocked. Can communicate with each other. As shown in FIG. 3, it is preferable that a sealing mechanism 350 is provided at the open ends of both the inner bag body 100 and the outer bag body 200. That is, the infusion bag / bottle storage bag 300 preferably has a sealing mechanism 350 at each of two opening ends facing each other. For example, the sealing mechanism may be a zipper composed of a male fitting part and a female fitting part. Such a zipper is desirable in that the open end can be freely opened and closed. In addition, the sealing mechanism is not limited to this, and the sealing mechanism may have a form such as a slider chuck, a wire fastener, or a surface fastener. In any form, it is preferable that the opening end of the inner bag body and / or the opening end of the outer bag body can be opened and closed by the sealing mechanism.

In the infusion bag / bottle storage bag of the present invention, the inner bag body is smaller than the outer bag body. In this respect, not only from the viewpoint of suitable storage of the infusion bag / bottle, but also from the viewpoint of its use, the side area S of the _inner bag body S is 80% or less of the side area S of the _{outer bag} body S. Is preferred (see FIG. 7). That is, “the area S _{inner bag} of each of the two opposing side bodies constituting the inner bag body” is 80% or less of the “area S _{outer bag} of each of the two opposing side bodies constituting the outer bag body”. It is preferable that As can be seen from the embodiment illustrated, the term "lateral area S _{within the bag} inner bag", which refers to the area of the main surface of the side body two opposite constituting the inner bag of an infusion back bottle storage bag Therefore, it means the area of the inner bag shown as a plan view in FIG. Similarly, “the side area S _{outer bag} of the outer bag body” refers to the area of the main surface of the two opposing side bodies constituting the outer bag body of the infusion bag / bottle storage bag, and therefore It means the area of the outer bag shown as a plan view in FIG.

As described above, it is preferable that the side area S _{within the bag} inner bag is less than or equal to 80% of the lateral area S _{outside bag} outer bag, therefore, "S _bag ≦ S _{outer bag} × 0. It is preferable to satisfy the relational expression “8”. More preferably, the side area S of the _{inner bag} body is 80% or less and 40% or more of the side area S _{outer bag} of the outer bag body (that is, “S _{outer bag} × 0.4 ≦ S _{inner bag} ≦ S _{Outer bag} × 0.8 ”), more preferably, the inner bag side area S _{inner bag} is 80% or less and 60% or more of the _{outer bag} side area S _{outer bag} (ie,“ S _{outer bag} × 0 ”). .6 ≦ S _{inner bag} ≦ S _{outer bag} × 0.8 ”). In such a case, even if the infusion bag is stored so that the connecting part 550 of the infusion bag and the bottle protrudes from the inner bag body 100, the connecting part can be easily stored inside the outer bag body (see FIG. 8). Therefore, it is desirable from the viewpoint of both storage and use of the infusion bag.

In terms of making it easier to fit the connecting parts inside the outer bag body, the non-overlap portion corresponding to the bag portion where the outer bag body and the inner bag body do not overlap is the plug body of the infusion bag. It is preferable that it is larger than the dimension of the attached connecting part. As shown in FIG. 8, in particular, the “non-overlap portion” (portion with “slash” in the drawing) located between the bottom of the inner bag body and the open end of the outer bag body is an infusion bag. It is preferable that it is larger than the dimension of the connection component 550 attached to the plug body. More specifically, as shown in the drawing, the length L _non-overlap between the bottom of the inner bag body and the open end of the outer bag body is “the length from the flange portion 550a of the connection component 550 to the tip portion 550b”. Is larger than the “L _{connecting part} ”, that is, the relational expression of L _non-overlap > L _{connecting part} is satisfied. If such a condition is satisfied, the connecting component can be reliably stored inside the outer bag body, which is desirable in terms of both storage and use of the infusion bag and bottle.

  As described above, the infusion bag / bottle storage bag of the present invention contributes to prevention of anticancer drug exposure. That is, the infusion bag / bottle storage bag of the present invention is particularly suitable for use as a bag for storing an anticancer drug bag or an anticancer drug bottle used for cancer treatment. In other words, the infusion bag / bottle storage bag 300 of the present invention is preferably an “anticancer agent bag / bottle storage bag”. Since it is such an “anticancer agent bag / bottle storage bag”, the outer bag body is particularly arranged such that at least one fold is provided in the outer bag body 200 or the outer bag body 200 is rolled up. It can be said that the 200 may have an inverted configuration. Moreover, since it is an “anticancer agent bag / bag storage bag”, it can be said that the inner bag body and / or the outer bag body is preferably a light-shielding bag body.

≪How to use infusion bag and bottle storage bag≫
Next, a method of using the above-described infusion bag / bottle storage bag will be described. The “use method of the infusion bag / bottle storage bag” of the present invention is characterized by handling of the bag when the infusion bag / bottle is stored.

  The method of using the present invention will be described with reference to FIGS. FIGS. 9 and 10 show changes over time of the infusion bag / bottle storage bag 300 when the infusion bag / bottle is stored. Here, FIGS. 9 (a) to 9 (c) and FIGS. 10 (a) to 10 (c) show the states at the same time as long as the alphabet attachments are the same.

  First, as a first operation of the method of use of the present invention, at least a part of the outer bag body is turned over with the outer surface facing inward so that the outer surface of the outer bag body is not exposed. Specifically, as shown in FIGS. 9A and 10A, while the outer surface of the outer bag body 200 is set to the inner side so that the outer surface of the outer bag body 200 is not exposed, at least a part of the inner surface of the outer bag body is formed. It is preferable that the outer bag body 200 is folded back so as to be exposed. In the illustrated embodiment, the outer bag body is turned over so that at least one crease is provided in the outer bag body 200. In such a first operation, a part of the outer bag body 200 is folded back so that the opening end of the outer bag body 200 is at the same position as or more than the bottom of the outer bag body 200. It is preferable to wrap.

  Instead of obtaining an inverted state by folding the outer bag body so that at least one crease is provided, the inverted state may be obtained by winding the outer bag body into a roll shape. That is, as shown in FIG. 6, the outer surface of the outer bag body is turned upside down with the outer surface of the outer bag body facing inward, and the outer end of the outer bag body is exposed. Do n’t worry. Even in the infusion bag / bottle storage bag that is rolled up in this way and turned over, at least a part of the inner surface of the outer bag body is exposed, whereas the outer surface of the outer bag body is exposed. Absent.

  The first operation of the method of use of the present invention is preferably performed prior to the preparation of an infusion solution for an infusion bag / bottle. That is, it is preferable that the outer bag body is folded before the preparation of the infusion solution for the infusion bag / bottle. For example, such preparation is a mixed preparation performed to obtain an infusion bag filled with an anticancer agent for each cancer patient, and the outer bag is turned over prior to the mixed preparation. . As described above, if the first operation is performed prior to the mixing preparation, the exposed surface of the infusion bag / bottle storage bag is formed in a temporary period after the mixing preparation and after the infusion bag / bottle storage. Becomes “a part of the inner surface of the outer bag body” and “a part of the outer surface of the inner bag body”, and the “outer surface of the outer bag body” that is not exposed can be prevented from being contaminated by the infusion solution.

  Subsequent to the first operation, the second operation is performed. That is, the infusion bag is inserted from the opening end of the inner bag body, and the infusion bag is placed inside the inner bag body. More specifically, as shown in FIG. 9 (b) and FIG. 10 (b), the infusion bag is stored through the opening end of the inner bag so that the infusion bag is inserted from the stopper side. Store inside the double bag of the bag.

  In the second operation, the “infusion bag / bottle that may be contaminated with the anticancer agent” is stored in the infusion bag / bottle storage bag. In other words, there is a possibility that anticancer drugs may scatter or leak during mixing preparation or priming by a pharmacist. In infusion back bottles that have undergone such mixing preparation or priming, anticancer caused by scattering or leakage The agent may be attached.

  Therefore, it can be said that when the infusion bag / bottle is stored inside the inner bag body in the second operation, the exposed surface of the infusion bag / bottle storage bag may be contaminated with the anticancer agent. In other words, during the second operation, the “exterior portion 315 of the outer bag body” and the “external portion 316 of the inner bag body” forming the exposed surface of the infusion bag / bottle storage bag may be contaminated with the anticancer agent. (See FIG. 9 (b) and FIG. 10 (b)). This is because the outer bag body is turned over by the first operation and the inner surface of the outer bag body is made the outer surface of the bag as an infusion bag / bottle storage bag. However, the outer surface of the outer bag body that does not form the exposed surface of the infusion bag / bottle storage bag is not the infusion bag / bottle storage bag during the second operation. It will not be contaminated with anticancer drugs during storage. This is because the original outer surface of the outer bag body is folded by the first operation so as to be turned inside out.

  In the second operation, it is preferable to store the infusion bag so that the connecting part attached to the stopper of the infusion bag bottle protrudes from the notch opening of the inner bag body. That is, it is preferable that the infusion bag is placed inside the inner bag body so that the connecting part penetrates the notch opening of the inner bag body. This is because the infusion bag / bottle storage bag is used as it is even during infusion using the infusion bag / bottle, and it is desirable to store the infusion bag / bottle in a form suitable for the use. As shown on the right side of FIG. 9B, the infusion bag / bottle connecting part 550 protrudes from the notch opening 140 until the flange part 550 a of the connecting part 550 contacts the bag around the notch opening 140. You may let me. The notch opening 140 functions as an “opening prevention opening” for the connecting part 550 of the infusion bag and bottle when the infusion bag and bottle are used, and accommodates the infusion bag and bottle in a form most suitable for it. This is because it is desirable. As shown in FIGS. 9 (b) and 9 (c), finally (after the “third operation” described below), the infusion back bottle projected from the notch opening 140 is used. The connection component 550 can be covered with the outer bag body 200.

  Subsequent to the second operation, the third operation is performed. That is, the outer bag body is turned over, and the infusion bag is accommodated in the double bag body composed of the outer bag body and the inner bag body. More specifically, as shown in FIGS. 9C and 10C, the “outside bag body inverted state” obtained by the first operation is returned to the original state. As a result, the “part 315 of the inner surface of the outer bag body” and the “part 316 of the outer surface of the inner bag body” that formed the exposed surface of the bag at the time of storage form the inner surface of the infusion bag / bottle storage bag. On the other hand, the "external outer surface of the outer bag body" that does not form the exposed surface of the bag during storage and is therefore uncontaminated forms the final outer surface of the infusion bag and bottle storage bag. Therefore, the infusion bag / bottle storage bag containing the infusion bag / bottle is not finally contaminated with the anticancer agent on the outer exposed surface, and the person who handles the infusion bag / bottle does not know after that. The risk of exposure to is eliminated.

  In the third operation, it is preferable that the user unwinds the inside-out state without substantially touching the original outer surface of the outer bag body. In other words, it is preferable that the person handling the infusion bag / bottom bottle unfolds the outer bag body under the condition that only the “part 315 of the inner surface of the outer bag body” and the “part 316 of the outer surface of the inner bag body” are touched. . For example, the opening end of the outer bag body may be picked with a finger in order to effectively release the inside out. As a result, the “inside-out state of the outer bag body” can be efficiently returned to the original state without substantially touching the “original outer surface of the outer bag body”. Therefore, in the present specification, the expression “not substantially touching the outer surface of the outer bag body” and similar expressions are used for the most part of the outer surface of the outer bag body (more specifically, the outer bag body, more specifically, This means an aspect in which the user does not substantially touch the outer surface of the outer bag body excluding the open end flow area of the bag body.

  It is preferable to seal the open ends of both the inner bag body and the outer bag body after releasing the inverted state of the outer bag body. That is, after the infusion bag / bottle is stored inside the inner bag body, the two opening ends of the infusion bag / bottle storage bag facing each other are closed by the sealing mechanism 350 (see FIG. 10C). Thereby, prevention of exposure of an anticancer agent can be aimed at more reliably. That is, the exposed surface of the infusion bag / bottle storage bag is formed during the second operation, and therefore may be contaminated with the anticancer agent, “part 315 of the inner surface of the outer bag body” and “inner bag” A part 316 "of the outer surface of the body is reliably cut off from the outside by the sealing operation of the two open ends.

(Method of using the present invention at the time of anticancer drug treatment)
The infusion bag / bottle storage bag is particularly suitable for use as a bag for storing an anticancer drug bag or an anticancer drug bottle used for cancer treatment. Therefore, the usage method in that case will be described in detail.

  In light of the treatment with the anticancer agent, it is preferable to turn the outer bag over as the first operation prior to the mixing preparation for preparing the anticancer agent. In other words, prior to mixing preparation for mixing anticancer drugs prescribed in chemotherapy for cancer patients, the outer bag body is turned inside out so that the outer surface of the outer bag body is not exposed. Keep the state. Specifically, as shown in FIGS. 9 (a) and 10 (a), the outer surface is made inward so that the outer surface of the outer bag body is not exposed, while at least a part of the inner surface of the outer bag body is exposed. In this way, the outer bag is folded.

  Next, as a second operation, the “infusion bag possibly contaminated with an anticancer agent” is stored inside the inner bag body of the infusion bag / bottle storage bag. After the storage, after the outer bag body is turned over and the folded state is released, the open ends of both the inner bag body and the outer bag body are sealed. Then, the infusion back bottle stored in the infusion back bottle storage bag is transported to the site where the infusion back bottle is actually used. For example, an infusion bag / bottle stored in an infusion bag / bottle storage bag is transported to the bedside of a cancer patient in a pharmacy department of a hospital. At this time, the outer exposed surface of the infusion bag / bottle storage bag containing the infusion bag / bottle is not contaminated with the anticancer agent, and the anticancer agent is not known by medical personnel or patients who handle the infusion bag / bottle. The danger of being exposed to is eliminated.

  Next, prior to the infusion of the anticancer drug using the infusion bag / bottle, the inside / outside state of the outer bag body of the infusion bag / bottle storage bag is released. For example, when the infusion bag / bottle storage bag is hooked on the hanging hook 400 using the opening 115, the infusion bag / bottle can be hung together with the storage bag. You may unravel the state and the folded state. It is preferable to perform infusion with an infusion bag in that state after the reverse state and the folded state are released. In other words, it is preferable to perform the infusion in a state where the infusion bag / bottle once stored in the infusion bag / bottle storage bag is not taken out of the infusion bag / bottle storage bag but is stored in the infusion bag / bottle storage bag. It is preferable to release the closed state of the open end of the outer bag body). As a result, the exposed surface of the infusion bag / bottle storage bag is formed during the second operation, and therefore may be contaminated with the anticancer agent, “part 315 of the inner surface of the outer bag body” and “inner Infusion with an infusion back bottle can be suitably performed without accidentally or accidentally touching a portion 316 "of the outer surface of the bag.

  When an infusion bag / bottle such as an infusion is used, the notch opening 140 of the infusion bag / bottle storage bag can function as an “opening prevention opening” for a connecting part of the infusion bag / bottle. That is, as shown in FIG. 4, when the infusion bag / bottle storage bag is used together with the infusion bag, the flange portion 550 a of the connection part 550 attached to the infusion bag is a bag around the notch opening 140. Therefore, even if the drip tube 570 or the like is accidentally pulled, an excessive force is generated between the connecting part 550 and the infusion bag 500. As a result, the connection component 550 is prevented from being detached.

  In the embodiment shown in FIG. 4, the connecting component 550 has a so-called “exposure prevention system”, but even if it does not have an “exposure prevention system”, it is connected by an infusion bag and bottle storage bag. Part separation can be prevented. Specifically, in an aspect in which the flange portion of the connection part cannot be locked to the bag body around the notch opening, another infusion bag / bottle equipment (for example, another flange product such as an infusion set bottle needle) 560) and the like can be used to prevent the infusion bag and the connection part from being detached. In this case, as shown in FIG. 11, another flanged product 560 such as an infusion set bottle needle (that is, a fixture having a bowl shape) is locked to the sealing portion at the open end of the outer bag body located below the flanged product 560. And the same effect as the above-mentioned notch opening part 140 can be acquired. That is, even if a downward force is applied to the connection component 550 due to accidental pulling of the drip tube 570 or the like, another flange product 560 such as an infusion set bottle needle is not sealed at the opening end of the outer bag body. Therefore, the force can be effectively absorbed. More specifically, the “reaction force” acts on the downward force due to the sealed portion at the opening end of the outer bag body, and the connection part 550 and the infusion bag 500 are mutually connected. The pulling force is substantially not generated.

  The infusion bag / bottle storage bag of the present invention can take various forms.

(Infusion device mounting mode)
The infusion device 520 may be attached in advance to the bag of the present invention. Specifically, as shown in FIG. 12, an exposure prevention device 550 such as a back spike may be attached in advance, or as shown in FIG. 13, an infusion set 540 including an infusion line or the like. May be attached in advance. In such a case, it can be said that the infusion bag / bottle storage bag / transport bag already includes the infusion device 520, so that not only the series of operations associated with infusion is simplified, but also the infusion device 520 It is excellent in organizing and storing. For the infusion device 520 to be attached in advance, an adhesive or an adhesive tape may be used, or an appropriate heat treatment such as heat sealing may be performed at the attachment portion.

  The “infusion device attachment mode” corresponds to a mode in which the infusion device 520 is attached to the notch opening 140.

Such a bag of the present invention can be defined as follows.
An infusion bag / bottle storage bag,
A double bag structure comprising an inner bag body positioned relatively inside and an outer bag body positioned relatively outside;
The infusion bag / bottle storage bag has two open ends facing each other, and one of the two open ends is constituted by the “open end of the inner bag body”, whereas the other open end is “ It consists of the open end of the outer bag body,
A notch opening is provided at the bottom of the inner bag body, and an infusion device or a part thereof is attached to the notch opening (particularly, it is attached in advance to the inner bag body via the notch opening. Infusion bag and bottle storage bag characterized by

  Preferably, as shown in the drawing, only the tip of the infusion device 520 or a part thereof (more specifically, “only the tip on the upstream side when assuming the infusion flow during use such as infusion”), for example, The infusion device or a part thereof is attached to the inner bag body so that the “tip portion of the tip” or the “connection portion with the infusion bag / bottle”) is positioned inside the inner bag body.

  In the “infusion device attachment mode”, since the infusion device 520 or a part thereof is attached in advance to the notch opening 140 of the inner bag body, the operation relating to the use of the infusion bag is further simplified. Specifically, in such “infusion device attachment mode”, (a) at least a part of the outer bag body is turned over so that the outer surface of the outer bag body is not exposed, and (b) the infusion bag is Insert from the opening end of the inner bag body and store the infusion bag inside the inner bag body. (C) Unwrap the outer bag body and double the bag body consisting of the outer bag body and the inner bag body. The infusion bag is stored inside the bag, and the infusion bag contained in the infusion bag is stored in the bag without taking it out of the infusion bag. When the infusion bag in (b) is placed inside the inner bag, the infusion bag and the infusion device 520 can be connected to each other in subsequent operations. (Ie, infusion bag Torr in like immediately before subjecting the suspended state and / or infusion in the field of infusion) so that the mounting operation of the infusion device 520 is omitted.

  Even in such an “infusion device mounting mode”, the bag can be suitably used as a transport bag for the infusion back bottle after mixing preparation, and the state where the infusion back bottle is contained in the bag is maintained as it is. Infusion with an infusion bag or bottle can also be performed. Furthermore, the bag of the infusion device mounting mode can be used as a bag for discarding the infusion bag without changing the storage state at the time of infusion. Therefore, even in the “infusion device mounting mode”, a series of operations for transporting, using, and disposing of the infusion bag / bottle is simplified as a whole, and those who use, transport, and dispose of the infusion bag / bottle are anticancer agents. Reduces the risk of exposure. That is, since the bag of the infusion device attachment mode is used for blocking from the outside after the infusion bag is contained, the risk of exposure by, for example, an anticancer agent is reduced.

  In particular, in the “infusion device mounting mode”, not only the infusion back bottle but also the infusion device connected to the infusion bag in the “stage after mixing preparation and before infusion” and / or “stage after infusion” are placed in a bag. be able to. Specifically, the infusion device can be stored in a space formed between the “bottom of the inner bag” and the “sealing mechanism for the outer bag”. Therefore, in the bag of the infusion device attachment mode, the volume of the space formed between the bottom of the inner bag body and the sealing mechanism of the outer bag body when the sealing is performed to close the sealing mechanism of the outer bag body is “infusion solution”. The relative positional relationship between the inner bag body 100 and the outer bag body 100 is preferably adjusted so as to be larger than the “volume of the infusion device connected to the back bottle”.

  Such “infusion device mounting mode” includes an mode in which an infusion device or a part thereof is attached to the bottom of the inner bag body through a “notch opening” using an appropriate means such as an adhesive or an adhesive tape. It can be considered. In addition, the bottom part of the inner bag body (especially the edge region of the bottom part) is hermetically sealed as a whole (sealing such that the opposing bag body surface parts are bonded together). Treatment may be performed, or a joining process may be performed in which the bottom portion of the inner bag body is hermetically sealed as a whole by subjecting the bottom portion of the inner bag body to an appropriate heat treatment such as heat sealing (FIG. 12). Or see the form shown in FIG.

  The usage of the “infusion device mounting mode” will be described in detail with reference to FIG. First, as the first operation, the outer bag body is provided in a folded state prior to the preparation of the infusion solution for the infusion bag / bottle. In other words, the outer bag body is turned over so that the exposed surface of the infusion bag / bottle storage bag substantially forms the “part of the inner surface of the outer bag body” and the “part of the outer surface of the inner bag body”. To. Next, as a second operation, the infusion bag 500 is inserted from the open end 110 of the inner bag body 100 and the infusion bag 500 is placed inside the inner bag body 100 (see FIG. 14A). More specifically, as shown in the figure, the infusion bag 500 is stored inside the infusion bag / bottle storage bag 300 through the opening end 110 of the inner bag 100 so that the infusion bag 500 is inserted from the stopper side. The infusion back bottle stored here may be an infusion back bottle charged with physiological saline. Alternatively, it may be an infusion back bottle in which an infusion such as an infusion is previously prepared, or more specifically an empty infusion back bottle.

  When the infusion bag / bottle is stored, the infusion bag / bottle and the infusion device 520 are connected (see FIG. 14B). Specifically, it is preferable to connect “the stopper of the infusion bag / bottle contained in the bag” and “the portion located inside the bag of the infusion device 520”. For example, an operation such as piercing a “tip portion (for example, a“ pointed portion ”) located inside the bag of the infusion device 520” into a “plug body (for example, a rubber plug) of an infusion bag contained in the bag” is performed. Make those connections. After the infusion bag / bottle is stored or after the above connection, the bag is preferably sealed by setting the sealing mechanism 350 of the inner bag body 100 to the “closed state”.

  When the infusion bag is filled with physiological saline (or an empty infusion bag) and the infusion device 520 is equipped with a device 528 for infusion, etc., the infusion bag is placed in a bag. After storing, an operation of charging an infusion such as an infusion solution into an infusion back bottle may be performed (see FIG. 14C).

  Next, as the third operation, the outer bag body is turned over and folded, the infusion device 520 is placed in the bag, the sealing mechanism 350 of the outer bag body 200 is set to the “closed state”, and the bag is sealed. Infusion device 520 is preferably housed in a space formed between “the bottom of the inner bag” and “the sealing mechanism of the outer bag”. The infusion bag 500 and the infusion device 520 contained in the bag are transported to the site where the infusion bag is actually used (see FIG. 14D). For example, an infusion bag / bottle stored in an infusion bag / bottle storage bag is transported to the bedside of a cancer patient in a pharmacy department of a hospital. At this time, the outer exposed surface of the infusion bag / bottle storage bag containing the infusion bag / bottle is not substantially contaminated with the anticancer agent, and the medical staff or patient handling the infusion bag / bottle is not aware of it. Risk of exposure to cancer drugs has been reduced. This is because, by the third operation for returning the “outside bag body 200 in the inverted state” to the original state, the “part of the inner surface of the outer bag body” and the “inner bag body” “Part of the outer surface” becomes the inner surface of the infusion bag / bottle storage bag, while the exposed surface of the bag does not form at the time of storage, and hence the “outer bag body's original outer surface” is not contaminated. This is because the outer surface of the back bottle storage bag is formed.

  When the infusion bag stored in the bag is transported to the site where it is actually used, infusion is performed with the infusion bag (see FIG. 14E). When performing the drip, the sealing mechanism 350 of the outer bag body 200 is set to the “open state”, and the infusion device 520 connected to the infusion bag 500 is partially removed from the bag. Then, as shown in FIG. 14E, the infusion bag 500 is infused with the infusion bag 500 maintained in the bag 300 as a whole.

  When the infusion is finished, the infusion bag 500 is discarded. In the disposal process, it is preferable to store the infusion device 520 connected to the infusion bag 500 as shown in FIGS. 14 (E) to 14 (G). Thereby, not only the infusion back bottle 500 but also the infusion device 520 connected thereto can be safely and integrally discarded. As shown in the figure, when using the bag 300 as a waste bag, the outer bag body sealing mechanism 350 is closed to seal the bag (and the inner bag body sealing mechanism 350 is opened). In such a case, it is preferable that the sealing mechanism of the inner bag body is similarly closed). As a result, the used infusion bag 500 and the infusion device 520 can be suitably shielded from the outside world, and the medical staff and patients handling the infusion bag are disposed with reduced risk of exposure to anticancer agents. Can be processed.

  Thus, when the infusion bag / bottle storage bag of the present invention is used as a waste bag, the infusion device connected to the infusion bag / bottle is stored inside the bag, so that not only the infusion bag / bottle but also the infusion solution. Bags can be discarded with the device packed inside the bag.

  In the disposal process, the opening 280 provided in the outer bag 200 may be used. The opening 280 is provided at the opening end B (210) and corresponds to “an opening for hanging the infusion bag / bottle storage bag”. As shown in the figure, after the drip, the entire bag is turned upside down, and the vicinity of the opening end B (210) is hooked on the hook portion using the opening 280. As a result, as shown in FIG. 14F, the open end B (210) can be opened. In particular, when only the opening 280 on one side of the outer bag body 200 is hooked on the hook portion, the opening end B (210) is suitably opened as shown in the figure, so that the infusion device 520 is stored inside the bag. (In other words, the disposal process can be easily performed by one person).

  As described above, even in the “infusion device attachment mode”, the bag can be used not only for storing and transporting the infusion bag, but also for infusion with the infusion bag. Furthermore, the bag can be used as a waste bag by maintaining the state where the infusion bag is stored in the bag after the infusion.

≪Method of manufacturing infusion bag and bottle storage bag≫
Next, a method for producing an infusion bag / bottle storage bag will be described with reference to FIG. In the production method of the present invention, step (i) is first performed. That is, as shown on the upper side of FIG. 15, the inner bag body 100 ′ and the outer bag body 200 ′ are prepared separately.

  Each of the inner bag body 100 ′ and the outer bag body 200 ′ prepared in the step (i) is preferably a bag body in which only one end thereof is an open end. That is, it is preferable to use a bag body having an open end only at one end as the inner bag body 100 ′ and the outer bag body 200 ′. In addition, each of the inner bag body 100 ′ and the outer bag body 200 ′ is preferably provided with a sealing mechanism at the opening end thereof. For example, an openable / closable zipper comprising a male fitting portion and a female fitting portion may be provided at each open end of the inner bag body 100 ′ and the outer bag body 200 ′.

  As the inner bag body 100 ′ and the outer bag body 200 ′ prepared in the step (i), commercially available bag bodies may be used as they are, or they may be individually manufactured through a molding method (for example, inflation molding).

  In the inner bag body 100 ′, “an opening 115 ′ for suspending the infusion bag / bottle storage bag” may be formed in advance. Similarly, a “notch opening 140” may be formed in advance at the bottom of the inner bag body 100 ′. That is, the opening 140 may be formed in the bottom of the inner bag body 100 ′ by partially cutting the inner bag body 100 ′.

  Subsequent to step (i), step (ii) is performed. That is, as shown in the middle of FIG. 15, the “open end of the inner bag body provided relatively inside” is projected from the “bottom part of the outer bag body provided relatively outside” to open the inner bag body. The end and the open end of the outer bag body are opposed to each other in the length direction. For example, a cut is made in the bottom portion of the outer bag body, and the inner bag body is partially protruded from the inner side to the outer side so that the opening end of the inner bag body passes through the cut portion in the bottom portion.

  Subsequent to step (ii), step (iii) is performed. That is, the bottom portion of the outer bag body and the inner bag body (particularly, the open end region) are joined to each other. More specifically, the joining process of the outer bag body and the inner bag body is performed so that the cut portion at the bottom and the inner bag body are sealed. A joining process will not be restrict | limited especially if the notch part and inner bag body of a bottom part are sealed. For example, you may perform the joining process of an outer bag body and an inner bag body using an adhesive agent or an adhesive tape. Alternatively, the outer bag body and the inner bag body may be joined by subjecting the bottom of the outer bag body and the open end region of the inner bag body to an appropriate heat treatment such as heat sealing.

  By going through the above steps (i) to (iii), one of the two open ends facing each other is constituted by the “open end of the inner bag body”, and the other of the two open ends facing each other is “outside” An infusion bag / bottle storage bag constituted by the opening end of the bag body can be obtained.

  In the manufacturing method of the present invention, after the step (iii), the outer bag body may be turned upside down with the outer surface inside so that the outer surface of the outer bag body is not exposed. That is, as shown in the lower side of FIG. 15, the infusion bag / bottle storage bag may be turned over so that the outer surface of the outer bag body is not exposed. More specifically, the outer surface may be turned inside so that the outer surface of the outer bag body is not exposed, while the outer bag body may be folded back so as to expose at least part of the inner surface of the outer bag body. In addition, you may attach | subject an outer bag body to a heat processing or a heating process from a viewpoint of hold | maintaining an inverted state suitably.

  As mentioned above, although embodiment of this invention has been described, it has only illustrated the typical example to the last. Therefore, those skilled in the art will easily understand that the present invention is not limited to this, and various modes are conceivable. For example, the following modifications can be considered.

  For example, the notch opening 140 provided at the bottom of the inner bag body 100 does not necessarily need to be “opened” in advance, and may be opened when the bag is used. Specifically, as shown in FIG. 16, a mode in which a cut portion 145 (for example, having a form like “perforation”) is provided at the bottom of the inner bag body 100 may be adopted. Such cut portion 145 is adapted to provide a break opening 145 'by breakage of that portion (see the lower view of FIG. 16). That is, when an external force is applied to the cut portion 145, the portion is torn and an opening 145 'is formed. Similar to the cutout opening 140, the break opening 145 ′ can be used as an opening for the connection piece 550 of the infusion bag 500. Specifically, the break opening 145 ′ serves to extend the connection part 550 attached to the stopper of the infusion bag and the bottle from the inside of the inner bag body 100 to the outside. In other words, when the infusion bag / bottle storage bag is used, the infusion bag / bottle storage bag 300 can be suspended so that a part of the connection part 550 is exposed from the inner bag body 100, and suitable infusion is possible. (See FIG. 4).

  In the manufacturing method of the present invention, the infusion bag / bottle storage bag is manufactured from the separately prepared inner bag body 100 ′ and outer bag body 200 ′, but the present invention is not necessarily limited thereto. For example, those skilled in the art will appreciate that infusion bags and bottle storage bags can be manufactured by integral molding depending on future optimization or progress of the molding process. That is, instead of the steps (i) to (iii), the double bag structure in which the opening end of the inner bag body projects from the bottom of the outer bag body in such a form that the inner bag body penetrates the outer bag body is integrated. The infusion bag / bottle storage bag of the present invention may be obtained by molding.

  The infusion bag / bottle storage bag of the present invention can be used as a bag for storing various infusion bags / bottles used at medical sites and nursing care sites. In particular, when the infusion bag is an anticancer drug bag or bottle used for infusion of cancer treatment, the present invention contributes to prevention of anticancer drug exposure caused by mixed preparation or priming. It can be suitably used on site.
